To all whom it may concern:

Be it known that we, MAX HARTMANN and HANS Kiicr, both citizens of the Swiss Confederation, and residing at Basel, Switzerland, have invented new and useful Dispersed Systems and Processes of Making Same, of which the following is a full, clear, and exact specification. .i-.-. k

The present invention relatesto a; process Ewample 2.

10 parts of a solution containing 10 per cent of the hydrochloric salt-of 'linoleyldiethyl-ethylene-diamide are. shaken for some time with. one part of m-cresol. A {colloidal .milkyf liquid is thus obtained of making dispersed system's byfusing which may'be diluted with Water-in any dispersing agent aqueous solution fdf'fsalts proportion.

The a am Z6 4 degree of dispersion reached by this process p 10 parts of a solution containing 10% of Varies according to the method of preparation from that of a coarse emulsion to 'the hydrochloride of oleyl-d ethyl-ethylenediamide are mixed with 4 parts of a soluthat of a colloidal solution. These salt'solutions may behave partly also as 'remarktion of silver nitrate of 10 per cent strength 'A milky, jelly-like. mass is thus obtained able protective colloids for the manufacture yielding by addition ofwater a solution of of colloidal solutions by chemical reactions, as for instance for the preparation of gold, silver chloride which is clear in transmitted light, opalescent in reflected light.

Eammple An aqueous solution of the Example 5.

A solution containing -10%*-of the hydrochlorideof palmityl-diethyl-ethylene-diamide is shaken with half of its volume of olive'oil, a stable emulsion being thus obtained...

After a short ebullition,- the liquid is cooled and tion of camphor of 20 percent .strength in olive oil, which has been brought by halogenation to the same specificweight asthe aqueous solution (1,0025 at (1). A milky emulsion is formed with particlesof 5 p. diameter on an average.- ThlS emulsion is stable for years without alteration, whereas one obtained by means of ordinary cam then dialysed. The colloidal silver solution thus obtained forms a coflee-brown liquid.

Example '7.

Example 8.

. Equal volumes of a solution" containing 10% of oleyl-diethyl-ethylene-diamide-hydrochloride and fish oil which latter has previously been treated with halogen are vigorously shaken for sometime. A stable very finely divided emulsion is thus obtained.

What we claim is: r

1. A process for the manufacture of dispersed systems, which consists in using as dispersing agent solutions of salts of acylated diamines.

2. A process for the manufacture of dispersed systems, which consists in using as dispersing agent aqueous solutions of salts of acylated diamines.

3. A process for the manufacture of'dispersed systems, which consists in using as dispersing agent solutions of salts of unilaterally acylated diamines.

4. A processfor the manufacture of discold. An

persed systems, which consists in using as dispersing agent aqueous solutions of salts of unilaterally acylated diamines.

5. As new articles of manufacture dispersed systems containing as dispersing agents solutions of salts of acylated diamines.

6. As new articles of manufacture dispersed systems containing as dispersing agents aqueous solutions of salts of acylated diamines.

7 As new articles of manufacture dispersed systems containing as dispersing agents solutions of salts of unliterally acylated diamines.

8. As new articles of manufacture dispersed systems containing as dispersing agents aqueous solutions of salts of unilaterally acylated diamines.

9. As a new article of manufacture a stable emulsion of camphor wherein a solution of camphor in halogenated oil is dispersed with an aqueous solution of the hydrochloric salt of the dimenthylester of diethylamino-ethylimino-dicarboxylic acid.

In witness whereof we have hereunto signed our names this 25th day of October,

1924, in the presence of two subscribing witnesses.
